Sherpa mini mount to fit the original Ender 3.

2021-12-09: Uploaded new STLs (v3), in the version from Nov 8th I mirrored the model upside down to minimise supports when I should have rotated it 180 degrees.
2021-11-08: Supports added to improve mount rigidity.

This mount provides clearance for an 11mm deep heat sink to be fitted on the back of the Sherpa Mini stepper motor (see picture). There's no room to fit a fan on the back, active cooling only possible from the side / underneath.

To install:

1. Press-fit M3 nuts into countersink on mount and brace underside.
2. Remove existing Bowden tube from hot end.
3. Insert short piece of PTFE tube into the top of your hot end.
4. Loosen the top left wheel bolt a few turns to allow the mount to side between the back plate and under the wheel bolt (see pictures).
5. Slide brace under RHS wheel spacer. Insert and tighten M3 bolt into brace on both sides.
6. Tighten wheel bolt (X axis wheel should be able to do 'wheelies', if it can't be turned, it's too tight).
7. Align Sherpa Mini over top Bowden tube in hot end and carefully press down to seat on Bowden tube and on mount.
8. Place 2 x M3 10mm bolts (a few mm longer also fine) through Sherpa mini to secure to mount (removing the Sherpa thumb screw can help provide access to mount hole below) and tighten M3 bolts into countersunk nuts.
